 * @plugindesc v1.03 - Replace actor commands with another under certain conditions.
 * @author Victor Sant
 *
 * @help 
 * ------------------------------------------------------------------------------
 * Actors, Classes, Weapons, Armors and States Notetags:
 * ------------------------------------------------------------------------------
 *  
 *  <command replace: 'replace', 'name'[, type]>
 *   result = code
 *  </command replace>
 *   This tag allows to replace the command with another command.
 *   This setting is divided on 4 parts:
 *     'replace' : name of the command to be replaced, always in quotations.
 *     'name' : name of the new command,always in quotations.
 *     type   : type of the command. (see bellow)
 *     code   : code that will enable or disable the replace.
 *
 * ------------------------------------------------------------------------------
 * Additional Information:
 * ------------------------------------------------------------------------------
 * 
 *  The code uses the same values as the damage formula, so you can use "a" for
 *  the user, "v[x]" for variable. The 'result' must return a true/false value.
 *
 * ---------------
 *
 *  - Command to Replace
 *  The name must be exactly the same as the command to be replaced, it is case
 *  sensitive and must be always in quotations. 
 *
 *  You can leave it blank (keep the quotations), if you do, the new command will
 *  be added, instead of replacing an old command.
 *
 * ---------------
 *
 *  - Command Name
 *  Name of the new command, must be always in quotations.
 *
 *  You can leave it blank (keep the quotations), if you do, you will remove the
 *  old command, without adding any new command.
 *
 * ---------------
 *
 *  - Command Type 
 *  The type of the command must be one of the follower values:
 *  attack, guard, skill, item, direct skill, direct item.
 *    attack : the new command is a physical attack.
 *    guard  : the new command is a guard action.
 *    skill type id : the new command is a skill list, id is the skill type Id.
 *    item type id  : the new command is a item list, id is the item type Id.
 *    skill id : the new command is a direct skill, id is the skill Id. *
 *    item id  : the new command is a direct item, id is the item Id. *
 *    mix action : the new command is a mix action. **
 *  *  The 'skill' and 'item' requres the plugin 'Direct Commands'.
 *  ** The 'mix action' requres the plugin 'Mix Actions'. The new mix command
 *     must be the same as the command name set here.
 *
 *  You can ommit the type, if you do, only the command name will be changed
 *  but it will keep the same function.
 * 
 * ------------------------------------------------------------------------------
 * Example Notetags:
 * ------------------------------------------------------------------------------
 *
 *  <command replace: 'Attack', 'Limit', skill type 4>
 *   result = a.tp == 100;
 *  </command replace>
 *   Replace the 'Attack' command with the command 'Limit', wich allows to select
 *   skills from the skill type 4, when the actor tp is equal 100.
 *
 * ---------------
 *
 *  <command replace: 'Magic', 'Sorcery', skill type 3>
 *   result = a.isDying();
 *  </command replace>
 *   Replace the Magic command with the command 'Sorcery' wich allows to select
 *   skills from the skill type 3, while the actor have less than 1/4 of the HP.
 *
 * ---------------
 *
 *  <command replace: 'Steal', 'Mug', skill 100>
 *   result = true;
 *  </command replace>
 *   Replace the 'Steal' command with the command 'Mug' wich allows use the skill
 *   id 100 directly from the command menu (require plugin "Direct Commands").
 *   The result is always true so this command will replace the steal command
 *   whenever it is available.
 *
 * ---------------
 *
 *  <command replace: 'Item', 'Mix', mix action>
 *   if (a.actorId() === 1 || a.actorId() === 2) {
 *       result = true;
 *   } else {
 *       result = false;
 *   }
 *  </command replace>
 *   Replace the 'Item' command with the command 'Mix' wich allows use the mix
 *   command name 'Mix' menu (require plugin "Mix Actions"), if the actor id is
 *   equal 1 or 2.
 *
 * ---------------
 *
 *  <command replace: '', 'Meditate', skill type 5>
 *   result = a.mpRate() < 0.5;
 *  </command replace>
 *   Adds the command 'Meditate', wich allows to select skills from the skill
 *  type 5, when the actor mp is lower than 50%.
 *
 * ---------------
 *
 *  <command replace: 'Passive', ''>
 *   result = $gameParty.inBattle();
 *  </command replace>
 *   Remove the command 'Paasive' while on battle.

 * @author Victor Sant

 * https://fungamemake.com/
 * https://twitter.com/munokura/
 *
 * 元プラグイン:
 * https://victorenginescripts.wordpress.com/rpg-maker-mv/replace-actions/
 *
 *
 * ===========================================================================
 * 必要プラグイン
 * ===========================================================================
 *
 * このプラグインを使用するには、下記のプラグインが必要です。
 * - VE_BasicModule
 *
 *
 * ---------------------------------------------------------------------------
 * アクター、職業、武器、防具、ステートのメモタグ
 * ---------------------------------------------------------------------------
 *
 *  <command replace: 'replace', 'name'[, type]>
 *   result = code
 *  </command replace>
 *   このタグは、コマンドを別のコマンドに置き換えることができます。
 *   この設定は4つのパートに分かれています。
 *     'replace' : 置換するコマンドの名前、常に引用符で囲まれています。
 *     'name' : 常に引用符で囲まれた新しいコマンド名。
 *     type   : コマンドの型を指定します。 (後述)
 *     code   : 置換を有効または無効にするコードを指定します。
 *
 * ---------------------------------------------------------------------------
 * 追加情報
 * ---------------------------------------------------------------------------
 *
 * コードではダメージの式と同じ値を使っているので、使用者には'a'、
 * 変数には'v[x]'を使うことができます。
 * 'result'はtrue/falseの値を返さなければなりません。
 *
 * ---------------
 *
 *  - Command to Replace
 * 名前は置換するコマンドと全く同じでなければなりません。
 * 空欄のままにしておくこともできます（引用符はそのままにしておきます）。
 *
 * ---------------
 *
 *  - Command Name
 * 新しいコマンドの名前は、常に引用符で囲む必要があります。
 *
 * 空白のままでも構いません(引用符はそのままにしておきます)。
 * そうすると、新しいコマンドを追加せずに古いコマンドを削除します。
 *
 * ---------------
 *
 *  - Command Type
 * コマンドの種類は、攻撃、防御、スキル、アイテム、ダイレクトスキル、
 * ダイレクトアイテムのいずれかのフォロワー値でなければなりません。
 *    attack : 新コマンドは物理攻撃
 *    guard  : 新しいコマンドは防御アクションです。
 *    skill type id : 新しいコマンドはスキルリストです。
 *    item type id  : 新しいコマンドはアイテムリストです。
 *    skill id : 新しいコマンドはダイレクトスキルで、IDはスキルIDです。*
 *    item id  : 新しいコマンドはダイレクトアイテム、idはアイテムIDです。*
 *    mix action : 新しいコマンドはミックスアクションです。**
 *  *  'スキル'と'アイテム'には、'VE_DirectCommands'プラグインが必要です。
 *  ** 'mix action' には 'VE_MixActions'プラグインが必要です。
 *     新しいmixコマンドは、
 *     ここで設定されているコマンド名と同じでなければなりません。
 *
 * 型を省略することもできます。
 * 省略した場合はコマンド名だけが変更されますが、機能は同じです。
 *
 * ---------------------------------------------------------------------------
 * メモタグの例
 * ---------------------------------------------------------------------------
 *
 *  <command replace: '攻撃', 'Limit', skill type 4>
 *   result = a.tp == 100;
 *  </command replace>
 * '攻撃'コマンドを'Limit'コマンドに置き換えて、
 * アクターのTPが100の時にスキルタイプ4からスキルを選択できるようにしました。
 *
 * ---------------
 *
 *  <command replace: '魔法', 'Sorcery', skill type 3>
 *   result = a.isDying();
 *  </command replace>
 * アクターのHPが1/4以下のステートで、
 * スキルタイプ3からスキルを選択できるコマンド'Sorcery'と
 * '魔法'のコマンドを入れ替えます。
 *
 * ---------------
 *
 *  <command replace: 'Steal', 'Mug', skill 100>
 *   result = true;
 *  </command replace>
 * 'Steal'コマンドを'Mug'コマンドに置き換えて、
 * コマンドメニューから直接スキルID100を使用できるようにします
 * 結果は常にtrueになるので、
 * このコマンドがあればいつでも盗むコマンドの代わりになります。
 *
 * ※'VE_DirectCommands'プラグインが必要です。
 *
 * ---------------
 *
 *  <command replace: 'アイテム', 'Mix', mix action>
 *   if (a.actorId() === 1 || a.actorId() === 2) {
 *       result = true;
 *   } else {
 *       result = false;
 *   }
 *  </command replace>
 * 'アイテム'コマンドを'Mix'コマンドに置き換えて、
 * アクターIDが1か2の場合、
 * 'Mix'メニューを使用できるようにします。
 *
 * ※'VE_MixActions'プラグインが必要です。
 *
 * ---------------
 *
 *  <command replace: '', 'Meditate', skill type 5>
 *   result = a.mpRate() < 0.5;
 *  </command replace>
 * アクターのMPが50%以下の時、
 * スキルタイプ5からスキルを選択できる'Meditate'コマンドを追加します。
 *
 * ---------------
 *
 *  <command replace: 'Passive', ''>
 *   result = $gameParty.inBattle();
 *  </command replace>
 * 戦闘中にコマンド'Paasive'を削除します。
